Question

find the second and third derivative of: 6/9+x

Answer 1

for my first derivative i had
\[\frac{ -6 }{ (9+x)^2 }\]

Answer 2

my second i had: \[\frac{ x^2-27x+6 }{ (9+x)^4 }\]

is that one right?

Answer 3

Hmm this is what I'm coming up with, It's probably easier to apply the power rule instead of .. quotient rule or whatever you did there :o
